RAM stores the memory that allows processors to access swiftly while carrying out functions to run a program. The number of programs that a computer can run at a time depends upon the capacity of RAM. SRAM stored data statically and does not require to refresh data every once in a white. It is a semiconductor based memory that stores data in the cross-coupled flip flops.
It is faster than DRAM but losses its memory once power is switched off. This version of RAM is also more costly. DRAM refreshes stored data frequently but its data is retained even after power is cut. This is also a semiconductor based memory and stores data in memory cells in the transistors.
They are cheap and are most commonly used RAM in computers, workstations and servers. Gaining an understanding of what each specification means, and what each part does, is the goal of this section. Reference Chart Bit b Smallest unit of storage possible. Actual value is Clock speed, a. Processor speed is often played up to be the major factor in a computer's overall performance. In rare cases this is true, but an average user rarely uses percent of his Central Processing Unit's power.
Things like encoding video or encrypting files, or anything that computes large, complex, numbers requires a lot of processor power. Most users spend most of their time typing, reading email or viewing web pages.
During this time, the computer's CPU is probably hovering around 1 or 2 percent of it's total speed. Startup time is probably the only time the CPU is under stress, and even then it's often limited due to the hard drive speed.
It is the driving force in the power the processor has all other things being equal. Higher MHZ chips use more power and produce more heat. It stores data right before and after it is processed. This is what makes a Pentium 3 or 4 chip different than a celeron chip x86 is the architecture type of all Windows based computers. All processors sold today for computers running the Windows OS operating system are 32 bit, meaning they process 32 bits of information each clock cycle a 1GHZ chip does 1 billion clock cycles per second.
Not all CPU's are x For example Apple computers use Motorola's chip design called PowerPC, which comes in both 64 and bit flavors. This is one reason apple computers can outpreform high-end PC's, despite their lower processor speeds.
Some of these terms only make sense to computer technicians and engineers. Others make a useful contribution to your ability to evaluate and compare computers, understand their specifications and select options with which to customize them. Of these terms, GHz and RAM each abbreviate critical concepts that apply to every computer you encounter. When you measure CPU speed or talk about system memory, these abbreviations take on important meanings.
One hertz consists of one cyclical movement between two states of a device or property. In computers, it defines the clock frequency that measures the timing of the operations your CPU performs. For a computer, one hertz goes by in far less than the blink of an eye. A component whose speed measures one megahertz performs one million operations per second.
At the gigahertz level, that speed climbs to one billion operations per second. To simplify the notation of this unit of measure, it abbreviates as GHz.
